Chairs

Having leather is a good choice at the island and if the dining chairs suit your table, that’s the most important. I think it’s more interesting them being different. Be sure to consider the maintenance of the light color.

Here's how the counter stools might appear on your space. Whether adding the matching chairs will work in the space has to do with the dining rable you select. I hope you'll select a table with a more monolithic base support and not more legs.

Thank you very much

Arhaus has a lot of options. IMO different would be better because of the close proximity.

I think those choices look like you tried to match and missed. I would do a chrome base swivel leather dining chair and keep the stools make sure the leather color for the dining room is not even close to the stools

I would follow Jan's advice -

- Selecting the matching dining chairs + counter stools = the two spaces won't look curated = hand-picked/selected. Identical styles (other than changing the upholstered portion of the stools/chairs) will make your home look like a page pulled straight from a mass-market furniture catalog rather than a collected, personal space.

- if you provide photos showing the surrounding areas, people will be able to see the style of your other furnishings. Your island + .dining table seating don't exist in isolation. I noticed that you posted a video - however, videos do not work on this site = if the video showed other areas of the home, we cannot see them.

Am thinking that the chairs and stools in matching fabric would be a better choice since they will be in close proximity.
